CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 12/938,351, titled BATTERY PACK, HOLSTER, AND EXTENDIBLE PROCESSING AND INTERFACE PLATFORM FOR MOBILE DEVICES, filed on Nov. 2, 2010, which is a divisional of U.S. patent application Ser. No. 12/357,262, titled BATTERY PACK, HOLSTER, AND EXTENDIBLE PROCESSING AND INTERFACE PLATFORM FOR MOBILE DEVICES, filed on Jan. 21, 2009, which claims the benefit under 35 U.S.C. §119(e) to U.S. Provisional Patent Application No. 61/021,897, titled BATTERY PACK AND HOLSTER FOR MOBILE DEVICES, and filed Jan. 18, 2008, the disclosures of which are hereby expressly incorporated by reference for all purposes.

Many mobile devices (e.g., mobile phones, digital assistants, mobile communication devices, handheld computing devices, personal music/video/content players and storage devices) are often powered by battery power sources. Such battery power sources are often housed within the mobile device and may be changed and/or recharged as needed. However, as more powerful mobile devices are designed, these tend to consume power more quickly, thereby shortening the time between charges. This tends to limit the usefulness of the mobile device since the user must find a power source to recharge the battery source and wait until it is recharged.

Additionally, after a certain number of recharges, a battery source may need to be replaced as it may no longer hold a charge. Oftentimes, it is not easy to replace a battery source as the mobile device may need to be disassembled or opened to reach the battery source.

Therefore, a way is needed to extend the time between charges of mobile devices and/or continue to power the mobile device even after an internal power source has been depleted.

In an alternative embodiment, the holster 602 may also include one or more rechargeable battery cells within the thickness of the back plane 604 that can power the mobile device via a device interface. FIG. 9 illustrates one example of a back view of the holster 612. An opening 902 may be formed on the back plane 604 to allow access to a reset or power button on the mobile device.

Third Embodiment

FIGS. 10-13 illustrate an alternative embodiment of a battery pack. The battery pack 1002 may include a back plane 1004, a first and second sides 1006 and 1008, a bottom side 1010, and an upper side 1012 which define a cavity 1004 for housing a mobile device. Additionally, the battery pack 1002 may include a first device interface 1014 and a second device interface 1016 (e.g., power connector, audio signals, control signal, data signals, etc.). In one embodiment, the second device interface 1016 may serve to provide power from one or more internal power cells (housed within the thickness of the back plane 1004). The internal power cells may be recharged via a third interface 1018 on the battery pack 1002. As illustrated in FIG. 11B, a mobile device 1102 may be inserted and housed by the battery pack 1002.

FIGS. 12 and 13 illustrate how the battery pack 1002 may be adapted to allow the mobile device 1102 to be inserted or removed. An upper portion 1204 may be movably separated from a lower portion 1202 of the battery pack 1002. The upper portion 1204 may slide on guides 1208 on both sides to create a space which allows the mobile device 1102 to detach from the interfaces 1014 and/or 1016. Once detached, the mobile device may be removed. Similarly, the space created by the upper portion 1204 sliding away from the bottom portion 1202 allows the mobile device to be inserted into the battery pack 1002.

The guides 1208 may also act as a stopper to prevent the upper portion 1204 from completely separating from the bottom portion 1202 once a separation limit is reached. Similarly, the guides 1208 may also include locking tabs that secure or couple the upper portion 1204 and lower portion 1202 together when they are in a closed position.

Fourth Embodiment

FIGS. 14-18 illustrate an alternative embodiment of a battery pack. The battery pack 1402 may include a back plane 1404, a first and second sides 1406 and 1408, a bottom side 1410, and an upper side 1412 which define a cavity 1404 for housing a mobile device 1426. Additionally, the battery pack 1402 may include a first device interface 1414 and a second device interface 1416 (e.g., power connector, audio signals, control signal, data signals, etc.). In one embodiment, the second device interface 1416 may serve to provide power from one or more internal power cells (housed within the thickness of the back plane 1404). The internal power cells may be recharged via a third interface 1418 on the battery pack 1402. As illustrated in FIG. 14B, a mobile device 1426 may be inserted and housed by the battery pack 1402.

FIGS. 16, 17, and 18 illustrate how the battery pack 1402 may be adapted to allow the mobile device 1426 to be inserted or removed. An upper portion 1502 may be movably separated from a lower portion 1506 of the battery pack 1402. The upper portion 1502 may slide on guides 1504 on both sides to create a space which allows the mobile device 1426 to detach from the interfaces 1414 and/or 1416. Once detached, the mobile device 1426 may be removed. Similarly, the space created by the upper portion 1502 sliding away from the bottom portion 1506 allows the mobile device to be inserted into the battery pack 1402.

To make it easier to insert and/or remove the mobile device 1426 from the battery pack 1402, the guides 1504 may include hinge points that allow the upper portion 1502 to fold relative to the bottom portion 1506, thereby allowing the mobile device 1426 to be removed or inserted with greater ease.

Speakers & Microphone

Another feature may provide for one or more speakers to be included as part of the battery packs or holster (illustrated in FIGS. 1-18). For instance a low-profile speaker may be housed within the back plane of a battery pack so that the sound may be emitted from the rear or sides of the battery pack. When a mobile device is inserted and coupled to the battery pack, it couples to an interface that electrically connects the speaker to the mobile device. The mobile device may send audio or sound signals to the speaker via an interface with the battery pack. This allows a user to listen to audio stored in the mobile device without the need for headphones.

Similarly, another feature may provide for one or more microphones to be included as part of the battery packs (illustrated in FIGS. 1-18). One or more microphones may be housed within the battery pack (e.g., back plane) so that they may capture sound from a user. The microphone may be electrically coupled to an interface that allows sending captured audio signals to a mobile device that may be coupled to the battery pack.

Additional Features

In some embodiments the back plane of the battery packs and/or holster of FIGS. 1-18 may house additional devices.

For example, the rear of the back plane may house an additional display screen extend the screen on the mobile device. The additional display screen may be electrically coupled to the mobile device (via an interface) to allow the mobile device to send images or video to the additional display screen.

In another example, the rear of the back plane may house a Braille input and/or output interface that electrically coupled a mobile device mounted within the holster or battery pack.

In yet another embodiment, the rear of the back plane may provide a keypad that serves as an input to the mobile device.

According to another feature, the battery pack and/or holster may provide an external interface (e.g., Bluetooth wireless interface, USB port, infrared port, etc.) that may allow the mobile device mounted in the battery pack and/or holster to communicate via that external interface. Thus the external interface may provide a different wireless interface than provided or supported by the internal system of the mobile device.

One or more of the features illustrated in FIGS. 1-18 may be rearranged and/or combined into a single component or embodied in several components. Additional components may also be added without departing from the invention.
